ON THE NATURE OF THE HETEROGENEOUS MINERALIZATION OF THE ARIADNE MASSIF OF BASITE ULTRABASITES (SIKHOTE-ALIN OROGENIC BELT)

In the south of the Russian Far East, a new promising type of sources of strategic and critically important metals (titanium, gold, platinum, niobium, hafnium, copper, antimony, etc.) has been identified - complex ores and placers spatially and genetically related to the Late Mesozoic synorogenic intrusions of ultrabasite basites of the Sikhote-Alin orogenic belt. An example of this is the Ariadne massif of ultrabasites, basites and granitoids, in the mafic part of which there is a manifestation of gold-titanium mineralization, in the exocontact - gold-antimony, and in the near-intrusive zone - gold-copper. It was found that mantle and crustal processes were involved in the formation of different types of ores. The obtained materials open up new opportunities for revaluation of the prospects of the raw material base of the strategic metals of Primorye.
